through shaft connections at is to'say In the construction of Fig. 1, the driving 95 3 the driving engine or motor will be provided shaft 1 and the driven shaft 2, are conwith a driving shaft and the driven machine nected by the flexible connection 3, which provided-'with a driven shaft which derives is shown as a spiral orlhelical sring mem- 45 its power from the driving shaft ,and from ber secured respectively to the iving and -fthe engine or motor which drives this driv- .driven shafts. Carried bythe dri shaft 100 in shaft. s y Y 1f is a sleeve 4 which is keyed to the riving v rdin to the present invention, the shaft to rotate therewith andwhich 1s also dri undv driven shafts are connected prevented from longgulcllinal movement with 60 throng an elastic coupl' or connection respectto the drivin ft. Carried by the 'whigh enables relative rotation ofthe drivdriven .Shaft 9 1S a bushmg 5 keyed to the op "`1'and driven`shafts with respect to each shaft so that it will rotate therewithbut httger, this relative rotation' increasing and free the slide longitudinally with respect decreasingy with in and decrease off thereto. The lsleeve 4 andbushing 5 are threaded as shown so that relative niove- `ment thereof will cau the bushing 5 to moved longitudinally upon the driven shaft -2. The bushing 5 acts upon one end of a lever 6 pivoted at 7, the end of this lever be ing suitably connected to the bushing as liv means of acircuniferential recess or groove in the bushing. The end of the lever 6 is to be connected to the drivin machine or en` gine or motor to regulate tie driving force, such as steam, Water, etc., in accordance with the well understood principles of gov-y erning such engines.

It will be evident that, with increase in load7 applied to' the driven shaft, this shaft will tend to'be retarded in its rotation so that the driving shaft will rotate angulariy with respect thereto until the flexible con- Y nection assumes a position or condition appropriete to the transmission. of the required power therethrough. With increased load upon the driven shaft and with resulting tendency toward decreased speed, an in creased amountof power must be applied to the driving shat to cause the driven shaft t0 still rotate Withuniform speed. The relative rotation of the driven. and driving shafts will cause the relative rotation of the sleeve f1 and bushing 5 so that the bushing 5 will slide `upon the driven shaft 2 and cause va corresponding movement of the regulating lever 6, by means of which the required coni trol of the drivin engine or motor 'will be effected so that t 1e corresponding increase or decrease in power ap lied to the driving shaft will make up for t e increasel .load on the driven shaft and still cause the desiredspeed of rotation thereof.

ln Fig. 2, a similar arran ement of the drivin and driven shafts is il ustrated with a simi ar flexible coupling or connection. In this construction, however', instead of providing a screw-threaded sleeve and hust lng, as in Fig. 1, the sleeve Ll' is provided with a `pin 8 which operates in a slot' or groove 9, in the bushing 5, This rslot or groove, instead of bein helical and regular, as the screvv-thread o Fi 1, 'is provided with a relativelyslight inc ination near the point of normal Ilocation of the pin 8, and with a greater inciinati'on at a greater distance from this" normal position, as clearly illustrated. Thei result of this arrangement is to cause but slight longitudinal movement of the sleeve 5 on the shaft 2, upon slight relative rotation of the driving and driven shafts; and to cause a relatively7 much greater lon itudinal movement of the 'sleeve or bus `ng 5"4 `when a very considerable dit ference 1n therelative rotation of the driving-and driven `shafts takes plac,

the control and regulation therefrom will be e'eeted 'in the manner above described.l

They Sleeve or bushing 5* of Fig. 2, acts u on a lever or operating arms 6 pivoted, at and The arrangement of Fig. 2 provides for more quickly and surely governing tl ie driving motor with quick and sudden or extern sive vuriationeL in the load and power required.

].n the construction of Fig. 3, the driving shaft 10 and driven shaft i1 are supported from n. eunmlon limaringg; la, the driven shaft extending into the hollow portion w" the driving shat and being supported ihefe through in the manor: r illustrated. The are ccnnered hy the spiral spring or coupling i3 which is connected with the driving vshaft by the extension l; and with the driven shaft hy suitable connecting members 15.

Mounted upon driving shaft is `a conducting ring il insulated therefrom and earrving en erin li. The driven *hait has n siioilariy' enlarged circular portion or disk il? which rotates therf-wvitii and which carries a resistance cie-- 'ment Q iinuilated therefrom. This resist-- ance elenien't is connected electrically' eviti.. e. ring 335! mounted on the driven and driving .shaft and insuiated therefrom. Suitable brush connections are provided with this ring and with the conducting ring 17.- '.lhe arm 18 is arranged to press yieldinfggljny upon the resistance element 20 and the-.slide there on with relative rotation ofthe ldriving and driven shafts i i 'i' Electrically connected with the ring i? is a source' of electric energy 22 of constant voltage. The connection therefromand connection from the ringv21 leedV to a suitable regulating series inotcirrsy en devicefor regulating the driving motor which drives the driving shaft. Any of the .well known arrangements adapted for this purpose majA be used. K

By wav of illustration, the reguiatmg motor is here shown connected to a "small generator 24 serving as a bucket in circuit with a Sourcecf substantially constant volt age, such as a. storage batteryfZ; and `the eld 26 of the main driving motorgetlie an mature 27 of which is connectedfto the ,drivin shaft 10 in ang,r ap 'ropriate manner.

to take care of the increased load on the driven shaft l1 and canse the latter to be brought up to the same Ispeed as the driving shaft 10. Decreased load with corresponding relative rotation of the driving and driven shafts in the opposite direction Will canse a corresponding increase in resistance, due to the resistance element 20 and Will cause a corresponding regulation of the main driving motor so that less power will be applied and the desired uniform speed still maintained.

It will he evident that various types of electrical connections are available for connecting vthe circuit illustrated in F ig. 3 with the main driving motorI to bring about regu ,lation thereof; the primary regulating' aotion taking place inthe structure illustrated in Fig. 3 by the relative rotation of the driving and driven shafts and by the relative positions of the arm 18 on the resistance element 20,

With the governor or regulator oi' the present. invention, the response to the changes in load will be immediate. The changes in load will cause immediate relative rotation of the driven and driving shafts, liet-anse of the elastic and iiexible connection therebetween; and this relative rotation will be transmitted, either by mechanical or electrical connections, to the driving engine or motor in the saine manner that governing action of common types o'l governors and regulators is transmitted to the driving engine or motor,

'Ihn governor or regulator of the present invention is one ot' high sensitiveni-:s's and one which provides a high degreeof regularity so thal- Iiniliorm action under varying lornls will be fiorsiti' obtained.
